the quick answer is no. a little bit longer answer is that dvd::rip (gui) with the transcode back end is not *too* bad. what i mean is that the gui is actually quite excellent, only it might be a little overwhelming for a person used to a much simpler dvd-shrink interface and options.
but if you could learn the gui, you could show them much easier than they could probably learn for themselves, having to sort through all the options, etc. iow, for most stuff, it could be *about* as easy as dvd-shrink, once they have learned a few basic concepts and are over the learning curve (most of which in this scenario you would be doing for them
).
